雅鲁藏布江-布拉马普特拉河是重要的国际河流，掌握该流域GDP数据空间分布状况及其变化信息，有助于制定合理的国际河流管理政策，维护区域稳定和发展。传统的GDP数据以行政区为统计单元，不便于国际河流相关信息的统计分析。本文以土地利用数据为基础，实现了雅江流域GDP数据空间化估算。结果表明，印度、孟加拉国在GDP总量方面均有一定优势，不丹和藏南的总量相对较小，但是增速最快，所有区域中第二产业所占比重均不大，说明全流域整体工业发展水平不高，而藏南主要经济来源是农业，其它产业比重较小。

The Tsangpo-Brahmaputra River is an important international river. Obtain the information of spatial pattern and change characteristic of Gross Domestic Product (GDP), will help to formulate reasonable international river management policy. However, traditional GDP data take administrative region as a statistical unit, is not convenient to statistic and analysis in international river regions. Based on the land cover data, we estimated the spatial distribution data of GDP in Tsangpo-Brahmaputra River basin. In Tsangpo-Brahmaputra River basin, India and Bangladesh have large GDP. Though the GDP in the ‘South Tibetan region’ and Bhutan is small, but growing fast. Compared to other economical section, the secondary industry accounted a small proportion in GDP, and this result indicated that the industrial development level is not high over the whole basin. In addition, agriculture accounted a large section in GDP, which is the major source of economy, and other section is small.
